 ## How to configure IPv6 on Linux with systemd-networkd
 
-`systemd-networkd` is the network manager of [systemd](https://systemd.io/). It is provided natively on most Linux distributions and can be used for the configuration of IPv6 with its DHCPv6 client feature.
+`systemd-networkd` is the network manager of [systemd](https://systemd.io/).
+Most modern Linux distributions ship with `systemd-networkd`.
+This method is appropriate when you:
+
+* run distributions that do not use Netplan
+* prefer low-level network configuration
+* configure containers or VMs manually
+
+Your IPv6 prefix is routed statically; DHCPv6 is used only for lease negotiation and DUID identification — not for address assignment.

 <Message type="tip">
   When specifying the IP address of your Dedibox, you need to enter it in [CIDR notation](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing). The netmask for the main IPv4 of a Dedibox server is `/24`, the netmask for a failover IPv4 is `/32`. The netmask for the IPv6 is `/64`.

+* Your /48 prefix must be subdivided into /64 networks
+* The host config generally uses one /64 per interface
